Heat stroke
Heat stroke
Heat stroke usually starts as heat exhaustion. The brain is unable to regulate body temperature, meaning that it cannot cool down once it has become too hot. Heat stroke occurs when core body temperature exceeds 40°C, often from spending too much time in the sun, participating in prolonged exercise or through a fever.
Elderly people and children are at higher risk as their bodies can struggle with heat regulation. It is very important to seek urgent medical attention as heat stroke can lead to organ damage or even death if left untreated.
